Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional methods are used to apply abrasive particles, then the manufacturing process is simple, but the distribution and orientation of abrasive particles are non-uniform, affecting performance
Solution Approach 1:
The patent controls the thickness ratio of the make coat (Tg/Ta ≤ 1.5) to optimize the distribution and orientation of abrasive particles. By adjusting the make coat thickness parameters, the invention achieves uniform particle distribution and controlled tilt angles without requiring complex manufacturing equipment or processes.
2Manufacturing precision
If the make coat is made thicker to ensure particle containment, then particle distribution is improved, but the make coat thickness ratio increases beyond optimal values, reducing manufacturing efficiency
Solution Approach 1:
The patent establishes an optimal make coat thickness ratio (Tg/Ta ≤ 1.5) that balances particle containment with manufacturing efficiency. This parameter optimization ensures adequate particle containment while avoiding excessive make coat thickness that would reduce manufacturing productivity.

AI summary
An abrasive article includes a backing; a make coat overlying the backing; and a plurality of abrasive particles overlying the backing and at least partially contained in the make coat; and a make coat thickness ratio (Tg/Ta) of not greater than 1.5, wherein Tg is the average thickness of the make coat at the sides of the abrasive particles and the Ta is the average thickness of the make coat.
